I use it on a few things. It kind of bugs me that the iOS version has to keep the little "location" arrow on in the top right because then I can't track which apps are using it but it's worth it if it helps me find a stolen phone. My only gripe with it is the price, or rather what you get when you pay for the premium version. If I'm paying for it I want unlimited reports. I don't care if it's more than they think I'll ever need, I want that peace of mind that no matter how long it takes me to get my stuff back the evidence I may one day need to give to the police isn't going to start being deleted because they're covering their own backs.
